COPY-HOLDER.

App1ication filed June 8, 1916.

To all whom 2'2? may concern:

Be it known that I, l/VILLIAM B. RHQADS,

a citizen of the United States, and a resi' dent of the city and countyof San Francisco, State of Callforma, have invented a new and usefulCopy-Holder, of which the following is a specification.

My invention relates to means for holding data which is to be copied.

An object of my invention is to provide a copy holder in which theindicator is're turned automatically from the bottom to the top of thecopy.

Another object of my invention is to provide acopy holder which maybefolded about the machine to which it is attached.

Another object of the invention is to pro vide a copy holder. in whichthe indicator adjustable to different thicknesses of the copy pad.

Another object of the invention is to provide a copy holder which isattachable to typewriters, linotypes, monotypes and similar machines andin which an indicator is moved a predetermined amount by depressing akey.

Another object of the invention is to provide a copy holder in which thespacing movement of the indicatoris adjustable to correspond with thespacing of the lines of the copy.

The invention possesses other features of advantage some of which, withthe foregoing will be set forth in the following de scription of thepreferred form of my invention which is illustrated in the drawingsaccompanying and forming part of the specification. It is to beunderstood that I do not limit myself to the showing made by the saiddrawings and description, as I may adopt variations of the preferredform within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a side elevation of my copy holder, showing its applicationto an or dinary typewriter.

Fig. 2 is a front elevation of the copy holder apart from thetypewriter.

Specification of Letters Patent.

Serial No.102,468.

Fig. is a fragmentary view on anenlarged scale ofa portion of my device.

Fig. 4 is a detail onan enlarged scale showing a portion of themechanism.

Fig. 5 is a fragmentary sectional view taken oaths-line 55 of Fig. 3.

Fig. 6 is a detail on an'enlarged scale showing a portion of themechanism.

Fig. '7 is a section taken on the line 77 of Fig. 6.

The copy holder of my invention is apdesired to maintain the matterwhich is to be copied in a convenient position before the eyes of thecopyist, but in this application, I will show and describe my inventionas it is used in connection with a typewriter.

My invention includes a frame comprise Patented Get. 30, 191W.

plicable in any circumstances in which it is ing the upri ht members 2,and the member 3 which is adapted to be rigidly secured to i atypewriter, preferably by clamp members 4: and The exact manner ofsecuring this frame to the frame of the typewriter is not" important.The essential thing is that it shall be rigidly secured to the typing machine and in eflect an integral portion thereof.

The copy holder in which the copy is retained is pivotally mounted uponthe frame 2-2 so that it may be folded down over the top of the typingmachine when the latter is closed up in its desk. The copy holder 7 andhaving a ledge 8 at its lower front edge. At the lower rear edge of theplate 7 a sleeve 9 is mounted on brackets 12 and 13 which securelyattach the sleeve to the plate. On the outside of the brackets thesleeveextends a short distance and these extensions form journals,bearings for which, 14, are arranged at the top of the frame members 2.The plate 7 is therefore adapted to be turned in the bearing-s14, and astop-15 is arranged on one of the frame members 2 to'limit the backwardturning of the plate.

Arranged in the sleeve 9 is a shaft 16, and a sprin'gl'r', coiledaboutthe shaft and attached at-ones end'to the sleeveand at' the preferablyconsists of a thin, metallic plate a other end to the shaft, resists theturning of the shaft in the sleeve. Fixed to the outer end of the shaft16 is a sprocket wheel 19 and a ratchet 21. A U-shaped member isdisposed upon the side of the plate 7 above the sprocket 19. At the topof this member is mounted another sprocket 25 and a chain 26 passesabout the sprockets, its front reach 26 being disposed in the memberwhich therefore acts a channel or guide in which the front reach of thechain 26 slides when the lower sprocket 19 is turned. 7

Means are provided for turning the ratchet wheel intermittently througha certain arc of revolution. A rocker 28 is loosely mounted upon the endof the shaft next to the ratchet 21. The rocker is retained in positionby means of the washer 31 hearing against a shoulder on the shaft andthe thumb nut 38 threaded on the shaft tight against the washer. Therocker is oscillated by means of the link pivoted thereto and to a lever36 pivotally mounted at 37 upon the frame extension 38. The forward endof the lever 36 carries a key 39 preferably suitably designated, anddisposed adjacent the typewriter bank of keys in a' conveniently reachedposition. A spring 4C1 operates to return the lever and rocker normalposition after each depression of the key, and a stop or loop throughwhich the lever passes limits the maximum movement of the lever. Therocker 28 carries a pawl 4A- which is retained in engagement with theteeth of the ratchet 21 by the spring 45. The teeth of the ratchet, andthe rocker are so disposed that depression of the key 39 effects avmovement of the ratchet in a direction such that the travel of theouter reach of chain 26 in the channel 24: is from the top toward thebottom of the plate 7.

llleans are provided for varying the amount of movement of theratchetwhen the key is depressed. A. portion a? of the chan nel Q-fi isextended rearwardly between the sprocket l9 and the ratchet 21.Preferably it encircles the shaft and is of circular form slightlylarger than the ratchet 21. On the shaft 16 between the plate 47 and theratchet 21 is loosely disposed a disk 51 preferably about the same sizeas the plate 47. Several holes are formed in the disk 51 on a circleconcentric with the shaft 16 and a spring pressed knob 52 carried by theplate 47 is adapted to engage in these holes so that the disk isprevented from rotating unless a certain amount of pressure is exertedto turn it; when the knob is disengaged from the hole in which ithappens to be ly ing. A portion of the edge of the disk 51 is formedwith a flange 54: which extends across the teeth of the ratchet 21. The

flange is so placed that in a portion of the recovery movement of therocker 28 the pawl ii rides up upon the flange and is therefore drawnout of engagement with the teeth of the ratchet. By var ing the positionof the flange the pawl li may be kept in contact with it for variousproportions of the operating movement of the rocker and allowed toengage the ratchet only for the balance of the movement. The spa ing andposition of the holes in the disk 51 are such that the disk, and hencethe flange, is held in predetermined relation to the movement of therocker so that the amount of movement imparted to the ratchet 21 by therocker may be controlled as desired. At the front, the disk is providedwith a pointer 56, which in conjunction with scale 57 fixed upon thelower end of the channel provides means for determining the position ofthe disk. The disk 51 is provided with an ear 58 which serves as ahandle for shifting it. A. spring pressed pawl 61 pivoted to the side ofthe channel engages the ratchet 21 on the recovery movement of therocker 2-8 and prevents the spring 17 from turning the shaft,

sprocket and chain back to first position,

Slidably arranged upon the front of .the channel 24c is a block ea. Theblock is attached to the chain 26 on the inside of the channel through aslot disposed in the front face of the channel and any movement of thechain 26 upon 'thesprockets is accompanied by a corresponding movementof the slidable block. Hinged upon the block 6% between the lugs 65thereon is a socket 66 and in the socket is arranged a line indicator.67 which overlies the plate 7 and any copy which is held thereon.provided with graduations similar to those on the spacing guide on thefront of the typewriter. The indicator is preferably reversible in thesocket to accommodate a very thick copy pad thereunder. A spring 69tends to turn the socket inwardly, thus keep ing the indicator pressedagainst the copy.

When there is need, the indicator may be swung outwardly about itspivotal mounting in the block against the resistance of the spring 69.

Preferably the parts are so disposed that when the indicator is in itstopmost position there is a'slight tension in the spring 17. It is nowapparent that successive depressions of the key 39 effect intermittentrotation of the ratchet and shaft and intermittent movement of the chain26 and the attached indicator, the latter moving from the top of thepla'e 7 toward the bottom in steps determined by the effective throw ofthe rocker 28 which as already explained is determined by the setting ofthe disk 51.

If the disk is set to l on the scale, each.

Preferably the indicator is I depression of the, key. lowers theindicator one line space. Ifthe disk is set to 3 on only to set the diskfor the spacing of the copy. A depression of the key when a line isfinished moves the indicator to the next line.

,Means are provided for automaticallyreturning the indicator to the topor first position when the limit of its advance across the copy support7 is reached. The lower part of the block 64: is provided with aslanting surface 72 and the pawl 61 is provided with a roller 73 mountedon a pin rigidly fixed in the pawl. The rollere-Xtendsacross the channel2 in a position to be engaged by the wedge surface 72 when the indicatoris at its lowest point. As the wedge passes under theroller, the latteris forced up, and the pawl 61 freed from the ratchet 21. A springpressedlatch 74 is arranged above the pawl 61 and as the pawl is liftedout of engagementwith the ratchet, the latch catches and holds the pawlin the disengaged position. Except for the engagement of the pawl id onthe rocker, the spring 17 would now cause a recovery movement of theshaft and chain, carrying the indicator back to the top ofthe plate, andthis occursas soon asthe pawl ii is'lifted off of the ratchet by theflange 5% during the recovery movement of the rocker which leaves theshaft free to rotate. A rubber stop 7 5 at the top of the channel 24receives the impact of the upwardly moving block 6% and makes therecovery practically noiseless. In order to release the latch 74 fromthe pawl, so that the pawl may again engage the ratchet on the downwardmovement of the indicator, a trip 76 issecuredto the chain at a pointwhich will engage the pin 77 and release the latch just as the indicatorreaches its top position. The pawl 61 is provided with a shortprojecting rod 78 whereby it may be disengaged from the ratchet by thefingers at anytime.

The top of the copy support 7 is provided with a clamp for holding thecopy. The clamp preferably consists of a rod 81 pivotally mounted at itsends and offset between the ends, so that different thicknesses may beheld by it. Preferably rubber friction pads 82 are provided on theoffset portion. The clamp is pressed against the work by means of aspring 83 arranged at one end of the rod 81.

If it is desired to backspace the indica tor, that is, set it back to ahigher line, the pawl 61 is moved out of engagement with the ratchetwheel, the thumb nut 33 being frictionally engaged by the fingers andthumb, so that the backward rotation ofthe shaft and sprocket maybecontrolled. ;The nut 33,:and attached shaft is allowed to turn intheifingers until the indicator reaches the desired height, where it isstoppeda'nd the latch 7% released from the pawl which then engages theratchet and prevents further backward movement.

It will be understood from the above explanation thatt-he plate 7 may befolded down over the machine about an axis coinciden-t with the axis ofthe shaft 16 and for this reason, none of the working parts aredisarranged or need to be detached because of said folding.

1 11102188 it is desiredyto start the feed of the indicator from a pointbelow its topmost position, the thumb wheel or nut :may be rotated bythe fingers to bring the indicator to the desired position.
